I've been running into this for the last year or so...single press on the cursor button on a third party remote sends double or triple command to the Samsung. I think I sometimes fix this on RTI by adding delays after command and making sure IR repeats only once..Other times I can't fix it. Today I was working on a URC remote and couldn't figure out how to fix on CPP. Is there a new set of commands I can get somewhere?....I bet Harmony wouldn't have this problem...sigh...
